Geodesic structure of the cosmological Levi-Civita spacetimes
Adam Tyc, Martin Zofka
We investigate the implications of the behavior of geodesics in static, cylindrically symmetric spacetimes with a non-zero cosmological constant. We consider the symmetries of thes…
Markov chains of -oriented triangulations of surfaces
Adam Tyc
We consider triangulations of closed -dimensional (not necessarily orientable) surfaces. Any minimal set of zigzags that double covers the set of edges provides a -orientatio…
Maximal cliques in the graph of -ary simplex codes of dimension two
Mariusz Kwiatkowski, Andrzej Matraś, Mark Pankov +1
We consider the induced subgraph of the corresponding Grassmann graph formed by -ary simplex codes of dimension , . This graph contains precisely two types of maximal…
On -monodromies in embedded graphs
Adam Tyc
We characterize all permutations which realize as the -monodromies of faces in connected simple finite graphs embedded in surfaces whose duals are also simple.
Chow's theorem for Hilbert Grassmannians as a Wigner-type theorem
Mark Pankov, Adam Tyc
Let be an infinite-dimensional complex Hilbert space. Denote by the Grassmannian formed by closed subspaces of whose dimension and codimension bo…
Zigzags in combinatorial tetrahedral chains and the associated Markov chain
Adam Tyc
Zigzags in graphs embedded in surfaces are cyclic sequences of edges whose any two consecutive edges are different, have a common vertex and belong to the same face. We investigate…
